Wikipedia Real Time Encyclopedia
Wikipedia is an online free content encyclopedia project helping create a world in which everyone can freely share in the sum of all knowledge. It is supported by the Wikimedia Foundation and based on a model of freely editable content.
Wikipedia is a live collaboration differing from paper-based reference sources in important ways. It is continually created and updated, with articles on new events appearing within minutes, rather than months or years. Because everybody can help improve it, Wikipedia has become more comprehensive than any other encyclopedia.
